✦ Synopsis

The speaker reviewed the progress made in the electrical transnfission of power for lighting and other industrial purposes, telephony, telegraph3, including wireless telegraphy, during the past thirty years and accompanied his remarks by numerous experimental illustrations o,f a novel and striking kind. He referred to the fact that the parallel coupling of alternating current transformers was first done in the Hall of the Institute in 1879 and exhibited replicas of these transformers in operation. A simple and elegant explanation was given of the fact that electromagnetic waves nsed in wireless telegraphy follow the earth's curvature. In referring to the possibilities of transmission by direct currents of high voltage the speaker exhibited a new form of static machine, the revolving parts of which consisted of aluminum wings stoutly attached to insulated hubs, the glass portion being stationary. This machi*~e operates on the Wimshurst principle, but has the advantage of being a thoroughly mechanical piece of apparatus.

After a vote of thanks to the speaker the meeting adjourned. R. B. OwE.x-s, .~ecrctar3'.
